SHimy 107 is jis which will bring the cranks to correct position as the priginal one was 103mm iso. If ou go for that shimy 107mm then you could still continue using the original cranks and the new chainring. That's what i was thinking. I tried all that on a sugino mesenger chainset which comeswith the same crapy fsa 103mm bb in a tricross.
